Given the transmitter and media (in the attachment) with a bandwidth of 20kHz, provide two digitizer and modulation combinations that are feasible together given the Nyquist capacity relationship.© BrainMass Inc. brainmass.com October 16, 2018, 10:41 pm ad1c9bdddf
Nyquist Capacity (referred to as Cn in further disucssion) is defined as 2*B*lg(#Signalling Levels or Symbols) bit/second. "lg" means log base 2.
So, we can compute the maximum bit rate for the medium as per Nyquist Capacity for each of the modulation choices, given the medium bandwidth Bmedia as 20KHz.
A. BPSK : It has two symbols or signalling levels.
Cn = 2 * 20000 * lg(2)
